Just putting it out there, I'm a digital artist & although my art isn't as advanced as the plagiarized artist's it isn't impossible to do that in less than 5 hours. My art usually takes about 3 hours max unless there's more than one character.
--->Aside from that, the poorly edited in text box made it obvious that it was plagiarism.

It took me less than 5 hours to do my Madoka Magica contest entry.
Going to attempt to enter this contest if I have time, school is painful.
